Happens every night, since im a night owl, I just cant sleep. I stay awake until like 1AM and fall asleep, and i also sleep on the top floor and the door to my house is on the second, every night, when my parents are asleep i hear the door creak or something downstairs makes a noise like a click or a footstep or sometimes a word i just cant make out, and i hide under the covers(a kid thing I never grew out of) for a good hour or so, and on some nights, when i hide under the covers I actually hear a creak or a footstep right by the door to my room and i just sweat and panic and am just paralyzed with fear. And then i fall asleep, wake up and the next night the cycle starts again...
